Abstract: The invention concerns a procedure for the bleaching of pulp, in which procedure an oxidating bleaching chemical containing chlorine is used. The essential feature of the invention is that the pulp is treated, either in conjunction with or before oxidation, with a lignin-modifying oxidation-reduction enzyme, such as the lactase produced by the white-rot fungus. The oxidating bleaching chemical used in the procedure may be chlorine dioxide or a mixture of chlorine dioxide and chlorine gas. The use of said enzyme reduces the amount of chlorophenols and other forms of organically bound chlorine in the spent bleach liquor, simultaneously lowering its chemical oxygen demand.

Abstract: A process for the removal of heavy metal ions and particularly cadmium and copper from phosphoric acid of a concentration in the range of 20% to 52% by wt P2O5 is described. The process consists in a treatment of phosphoric acid with a reducing agent and a thio-organophosphene reagent, the heavy metal ions being retained on a solid adsorbent. According to one embodiment the process is carried out during the production of wet-process phosphoric acid, the calcium sulfate co-produced being the adsorbent. According to another embodiment,a solution of phosphoric acid, obtained by mixing a filter acid phosphoric acid with a more concentrated phosphoric acid solution, is treated according to the process, using an adsorbent selected from the group consisting of calcium sulfate, active carbon and aluminum silicates. The thio-organophosphene reagents are selected from tri-n-propylphosphene sulfide, diisobutyl dithiophosphene sulfide, tri-n-octylphosphene sulfide, dicyclohexyl phosphene sulfide, diisobutyl dithiophosphinate and dicylcohexyl dithiophosphinate.

Abstract: Scrap poly(ethyleneterephthalate) is converted to useful amine and diamine monomers such as para-xylylenediamine, 1,4-bis(aminomethyl)cyclohexane and 4-aminomethyl benzoic acid for the production of various polyamides. The conversion of poly(ethyleneterephthalate) to diamine monomers is achieved by a three step process involving (a) ammonolysis of the poly(ethyleneterephthalate) to produce terephthalamide and ethylene glycol; (b) pyrolytic dehydration of the terephthalamide to produce terephthalonitrile; and (c) hydrogenation of the terephthalonitrile to produce the para-xylylene diamine and/or 1,4-bis(aminomethyl)cyclohexane. The conversion of poly(ethyleneterephthalate) to 4-aminomethyl benzoic acid involves the steps of (a) ammonolysis of the poly(ethyleneterephthalate) to produce terephthalamide; (b) partial pyrolytic dehydration of said terephthalamide to produce 4-cyanobenzoic acid; and (c) hydrogenation of said 4-cyanobenzoic acid to produce 4-aminomethylbenzoic acid. The process of the present invention permits the conversion of low value PET scrap such as beverage bottles, fibers and film to relatively high value and relatively pure diamine monomers and ethylene glycol.

Abstract: The invention relates to low delivery cigarettes, usually having a mainstream particulate matter delivery of about 9mg or less. The cigarettes(1) comprise a rod (2) of tobacco material and a filter element (3). The filter element (3) comprises an alkali filter material section (4) having a loading level of less than 12% by weight of the section. The characteristics of the cigarettes (1) are arranged so that, when smoked, the alkaline filter material is exposed to an amount of smoke acceptable to achieve an increased perception of smoke impact. This is usually achieved by using a low particulate matter potential rod. In this way the moisture free dry particulate matter (NFDPM) to nicotine ratio is decreased compared with control cigarettes having the same cigarette characteristics without the addition of alkaline filter material to the filter element. <IMAGE>

Abstract: Composite materials (17) of reinforcing fibers are impregnated with polymeric matrices which may contain fillers and are then cured or thermoformed. As curing or thermoforming proceeds, dielectric detection is employed to closely monitor critical process events such as the release of volatiles, chemical reactions such as cross linking, melting and solidification. Curves are generated by plotting factors of the dielectric loss of the polymer matrix against time during the process; these plots have a distinctive shape or signature characteristic of the particular polymer matrix being processed. These distinctive features or signatures have been found to correlate with critical process events and are stored in a computer. During a cure cycle, the computer actuates the controls of the heating system so that the appropriate process actions or modifications will occur at the optimum time. The process controls are thereby adapted to produce an optimized high quality product. <IMAGE>

Abstract: In a step conveyor (not shown) for fresh boxless sand moulds (not shown) and comprising at least two sets of interdigitating parallel bars (3,4) adapted to support and move said sand moulds, the main novel feature consists in that the top of each bar (3,4) is covered or coated by a layer of a material with a considerably lower thermal conductivity than that of steel, in the example shown consisting of a top rail (9) secured to a base member (7) by means of screws (10), said top rail being made of a suitable synthetic resin, such as low-pressure polyethylene with ultra-high molecular weight. With this arrangement, the tendency for moisture from the fresh sand moulds to condense on the conveyor bars (3,4) is considerably reduced or eliminated, thus reducing or eliminating the tendency for sand from the moulds to adhere to the conveyor bars. <IMAGE>
